Error flashing Xavier NX on a A203v2 carrier board

Products & Technology
#1

Hi,
I try to flash a Xavier NX SOM on a A203v2 carrier board.
I replaced the dtb file (as there seems to be only one file to replace) and I tried to flash the board with the following commands (both failed).

sudo ./flash.sh -r jetson-xavier-nx-devkit-emmc mmcblk0p1
sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1

It is always the same error. Here is the end of the log:

Failed flashing t186ref.

flashing with the sdk manager fails as well.
I use Jetpack 4.6 [Rev 3] and it does work with a TX2 NX on a A203v2 board.

thank you

Hi, I should have posted the workaround.

I used Jetpack 4.6.1 and it did work. I had issues later with apt-get which was kind of broken so I used Jetpack 5.0.1 DP and it’s working great. I appreciate Ubuntu 20 and cuda 11.X.
